Small Bathroom Ideas: 25 Clever Design Solutions for Compact Spaces

In my years writing about Australian bathroom renovations, I have had a realisation, small bathrooms don't have to feel small. Some of the best and most creative small bathroom ideas I have come across and written about have been less than 3 square metres in size, and are classier and better designed than some double the size. If you are going to build a compact ensuite or small main bathroom, small bathroom ideas have changed dramatically since the days where small meant you had to just fit everything you needed into your room.

Why Small Bathrooms Deserve Smarter Design Choices

Most Australian bathrooms are 5 to 8 square metres, with most ensuites less than 4 square metres. At that scale your decisions count more, because one poor design choice could mean you feel boxed in and cramped in the room, while the right decisions can make it feel open and spacious. Small bathroom design means editing. It means being able to see what is required versus what is just a "nice to have". The freestanding bath might look amazing on an image board, but in a 3.5 square metre room, it might feel like the room has been taken over. A walk-in shower with frameless glass feels like it doesn't take up any space at all.

Storage Solutions That Actually Work in a Tight Space

Bathrooms are the same with storage, big or small, but storage is really a question about how much. When there isn't enough, benchtops can quickly fill with clutter, and the room starts to feel chaotic. My advice is that in small or large rooms, start small with the shower niches, 300 x 600 mm is your standard size that can lie flat with the tiles without any bulging. The niches are great for storing your toiletries without impacting your flooring.
I also always come back to using mirror cabinets, which can double as the medicine cabinet as well and are something that should be included in your small bathroom design. LED shaving cabinets typically come in 600 mm to 900 mm widths and prices generally start from $390.
It is also the perfect time to consider your options for cabinetry drawers, as vanity under-drawer storage is a real game changer. Drawer storage with soft-close runners is always a bonus because there isn't the clutter of shelves, everything is right in front of you; you can also fit the drawers right into the full depth of the cabinetry, not cupboards and doors. Wall-hung vanities from CETO or Aulic are built well with cleverly designed internal storage components.

The Best Tile Options for Small Bathrooms

My number one advice when looking at small bathroom tile ideas is to go larger than you think, because bigger is actually better. Larger tiles such as 600 x 600 mm, or even 600 x 1200 mm tiles mean less grout which creates a more open look. The lighter the colour palette, such as light whites, pale greys or light greens, the more light it is going to reflect which will open the walls visually.
You can have some drama or pattern in one wall behind the vanity, but make the rest of the bathroom tiles simple, neutral, and in lighter tones. Also consider your tile layout and patterns in the bathroom, such as laying rectangular tiles that are stacked vertically. Running a tile size of 200 x 600 mm vertically on your walls can make the room look longer and lift the ceiling visually.
If you want the look of modern tiles without the worry of water, slip and wear, choose a matte or satin finish.

Vanity and Fixture Ideas for Compact Spaces

Since the vanity will probably be the most sizable fitting in a small bathroom, it is essential to ensure the size is right. By choosing a wall-hung vanity, you open up some visible floor space that creates the illusion of a bigger bathroom.
If your bathroom is below 4 square metres in size, opt for a 600 mm vanity. You will find that a PVC cabinet will start at around $150 in this size. However, you should be expecting around $400–$800 for a plywood vanity with a ceramic top, depending on the brand and finish.
If you find yourself in a corner (and I mean literally), consider if there is a vanity small enough to squeeze in the area left unused. Narrow vanity cabinets and corner vanities are great for the often awkward corners of small bathrooms. A bathroom vanity for small bathroom layouts typically comes in widths between 400 and 600 mm and usually incorporates a basin.
Another consideration is a smaller sized toilet suite. A back-to-wall toilet with concealed cisterns can save about 100 mm of depth over the more traditional close-coupled type of toilet suite.

Layout Tricks That Make a Small Bathroom Feel Bigger

In the layout, there are some compact bathroom ideas that are just as effective in increasing the apparent size of a small bathroom. By swapping out a swing-out door for a pocket door or even a sliding door, you save around 800 mm of wall space, making a big difference in what fixtures you can afford to purchase.
A frameless glass shower screen in preference to a shower curtain also allows your eye to flow across the room with ease. A full wet-room layout that incorporates an open floor drain and a flush floor shower is a great small bathroom layout solution.
Mirror placement seems to get less consideration in a small space than it deserves. A full wall-width mirror mounted above the vanity will help to bounce the light around the room and also create the illusion of depth in the bathroom. In particular, a vanity for corner spaces helps even the tiniest bathroom to feel bigger.
Another common oversight is consistent flooring choices. By tiling the entire room with tiles that flow from the shower floor directly onto the drain, this lack of visual separation makes a small bathroom feel seamless too.
